Women with polycystic ovary syndrome (PCOS) have high levels of androgens in their blood, which has been assumed able to affect fetal development during pregnancy. An international team of researchers...
View ArticleTreating colon cancer with vitamin A
A leading cause of cancer deaths worldwide, colon cancer is famously resistant to treatment. There are many reasons for this, but one has to do with a group of persisting cancer cells in the colon that...
View ArticleTo preserve its memories, the brain must regulate its neural networks
Memory, i.e. our ability to record, to preserve and to recall our past experiences, makes up one of the most fundamental and fascinating abilities of our brain. For over forty years, neuroscientists...
